This invention relates to improvements in wringers.

The invention has s ecial reference to devices serviceable to e ect relative tensioning between wringer rolls and to provide quick release of said tension relation.

The invention lies principally in the manner of associating operating parts, whereby the act of joining framing parts of the wringer will operate directly to effect tensioning of the rolls, and similarly, release of engagement between said framing parts will relieve such tension without danger of wringer parts being wholly detached from the wringer frame ,under the stress accompanyin such release.

Anot er object of the invention is to provide for the removal of the upper roll member withthe removal of a detachable head or u per frame member.

T e invention also includes special cam acting connector means as between the main and a top frame member that will operate tov produce tension between rolls.

Other features of invention reside in the detail structure of operating parts and the relative relationing of the parts to reduce the results sought, all of which will c more particularly described. g

Fig. 1 shows in vertical section the structure and relative arrangement of parts of the wringer and its association with a driving head adapted to be connected with a, washing machine structure (not shown).

as Fig. 2 is a detail view showing the upper end portion of a wringer side frame member and a connector member.

Fig. 3 is a top view of the same subject matter disclosed in Fig. 2.

The nature of the invention will be most quickly understood by immediate reference to the drawings. Let it be understood that in the embodiment of the disclosure herein. there is a wringer frame made up of a base,

channel portion 10 and end frame members 11, which latter are slotted at their inner sides so as to provide the opposite flanges 11. Roller bearings 12 are mounted inthe side frame members for support of the lower roller 13, the shaft of which extends at one end through a suitable openingin the side frame member for engagement with a driving member such as the socket connection 14, which is actuated from a suitable source. A

as spring 15 is mounted in the base member and cooperates at its ends with vertically slidable connectors 16, which are positioned against the outer walls of the said frame member and retained by the headed rivets 17, which slide in slots 18. The connectors are slotted at their upper ends and carry rollers 19. The upper ends of the connectors are furcatedand 'ashioned into ferrules 20 for supporting a pin upon which roller 19 is journaled. The wringer head frame 20 is adapted to fit over the upper ends' of the side frame members 11 and house the proectmg portions of the connectors 16. The head carries the upper bearings 21,in which is journaled the pressure roller 22, the same being held in bearings by the pins 24. A stub shaft 25 is journaled at the top of the head 20' for rotation by means of the crank 26' and carries at its lower end a toggle link 27. To the toggle link are pivotally connected the connector links 28, which extend laterally through the head member, and through slots in bearings 21 in which said l1nks are supported on rollers 29. When the head is positloned on the frame, the shaft of roller 22 is received in the slots of the side frame members so that the pressure roller may contact the roller 13 and have the necessary freedom of vertical movement. The connecting links 28 align with the slots in the upper ends of the connectors 16 so that upon rotation of the stub shaft 25 the connecting links will be moved outwardly and their cam fashioned outer ends will be projected under the rollers 19. The wedgin action thus exerted on the rollers 19 wi cam the connectors 16 upwardly and stress the spring 15, the reaction of which is transmitted through the connectors and connecting links 28 to the upper bearingsizl and 05 the pressure roller 22 so as to press the latter into co-operation with the roller 13, under yielding pressure. By rotation of shaft 25, the connecting links 28 may be retracted from engagement with the rollers 19 and the 100 head thereby freed tov permit its complete removal, together with the pressure roller 22' from the frame. The roller 13 likewise may be removed from the frame by lifting it throu h the side frames at such an inclination t at the end of the shaft may be withdrawn from the 's'ocket 14., 30 is a screw member operating in a threaded opening in spring bar 15 and may be turned to increase or the tensional activity of said no spring. 31 are stops having engagement connector bars 16, which latter are normally seated upon stop members 31. The screw 30 is adjustable to produce the desired tensionalactivity of spring bar 15. Roller 13 is entered within the frame, with its left hand end in interlocked engagement with driving member 14. Roller 22 and topframing member 20 constituting a unit structure, are adapted to be connected with the main frame by simply entering the roller and causing the top frame'member to overlie the upper end'of the side members of the main frame, and thereupon locking arms 28 are adapted to be projected outwardly through the action of hand lever 26 to cause the outer cam fashioned ends of said levers to enter the slots in the upper ends of con-' nector members 16, under resistance of rollor member 19, which action serves to project said rollers and the connector members upwardly, thereby effecting an interlock-betwen the side and top framing members and at the same time flexing spring member 15 upwardly to induce tension between rollers 13 and 22.

The wringer'parts having been assembled in the manner above described, striking lever 26 will occupy the position shown in Fig. 1 and the wringer portion may be carried forward until it is desired that the tensio'ned relationship of the roller members he terminated or to accommodate the removal of the top framing member, thereupon by a simple stroke upon either arm member 26, locking members 28 will be withdrawn from enga ement with connector members 16,

there y relieving the tension and permitting the top framing member, together with roll 22 to be entirely removed from the main wrin er frame.
